In line with empirical evidence from seminal research, we assume that emotions and social norms play a key role in consumers’ decisions. To this end, we develop a socio- cognitive agent to examine the psychological and sociological factors influencing consumer decision-making. The underlying assumptions are operationalized in a decision model t...

In developing cognitive agents using a functional model of the human mind as their decision unit, a model of motivations and valuations is needed as the basis for the agents' decision making. This enables agents to cope with their internal and external world while pursuing their own agenda. We show that a technical model based on the psychoanalytic...

The examination of AGI agents is an interdisciplinary challenge. This is particularly the case for their foundations, assumedly (in compliance with Damasio) drives and emotions. We demonstrate how these foundations of a human-like control system are tested using simplified exemplary cases as test-specifications. After showing how we model the requi...

The computational paradigm in Cognitive Science, which the AGI approach revives, provides a powerful methodology of examining human information processing by testing assumptions in computer simulations, and enables technical applications with human-like capabilities. Nevertheless, intensive interdisciplinary collaboration and the development of a h...

Zusammenfassung Digital Credentials sind digitale Nachweise, die in verschiedenen Kontexten erbrachte Lernleistungen und Qualifikationen erfassen. Die automatische Verifizierbarkeit solcher Nachweise bildet die Grundlage für ihren sicheren und effizienten Austausch.

Versorgungskontinuität ist ohne Informationskontinuität nicht möglich. Das wird besonders in der pflegerischen Versorgung deutlich: Pflegebedürftige Menschen haben regelmäßigen und häufigen Kontakt zu unterschiedlichen medizinischen und pfle- gerischen Dienstleistern. Ein Mangel an Abstimmung und Ver- netzung zwischen ihnen geht nicht nur zu Lasten...

Background: Detecting manifestations of spatial disorientation in real time is a key requirement for adaptive assistive navigation systems for people with dementia. Objective: To identify predictive patterns of spatial disorientation in cognitively impaired people during unconstrained locomotion behavior in an urban environment. Methods: Accel...

This paper addresses psychologists – psychoanalysts in particular – and engineers, as well as others with an interest in technology and a proclivity for critical thinking. We hope to grasp the attention of persons who are skeptical or even uneasy with regard to modern electronic machines. It is important to realize that the mathematician and inform...

Agent-based modelling (ABM) proves successful as a methodology for the social sciences. To continue bridging the micro-macro link in social simulations and applying ABM in real-world conditions, conventional and often simplified models of decision-making have to be utilized and extended into psychologically plausible models. We demonstrate the cont...

An autonomous agent must know where it is, which objects are in the nearby surrounding area and where it can find already seen, far away objects. On the basis of the existing cognitive architecture Simulation of Mental Apparatus and Applications (SiMA) at the Institute of Computer Technology (ICT) we show, how cognitive architectures can get extend...

Fitting a bionically inspired cognitive model to a technical application domain is a challenging task. This work presents the fundamental steps in applying the SiMA-based cognitive model ECABA to the domain of building automation. The focus of the paper is to show the initial steps and challenges for implementing the human inspired mechanisms of dr...

Cognitive architectures as frameworks for integrated computational models of the mind often focus on human reasoning capabilities, and sometimes are extended by theories of emotion. The SiMA-C approach starts with low-level mental processing and bases high-level process on its low-level foundation. With the aim of developing a unified model with fu...

This paper provides a theoretical specification of a case-driven methodology to develop and examine mental architectures¹. The challenges of regular interdisciplinary collaboration are tackled by combining casuistry, use-case driven software engineering, and simulation in a novel way. A shared representation of the problem space by exemplary cases...

The operation of buildings holds the potential for significant energy savings and high flexibility during operation without affecting indoor comfort. The leverage for this potential is the building automation system, which can modify and optimize operation without the need of investments in energy systems or refurbishment of the envelope. The chall...

Das Projekt SiMA (bisherige Bezeichnung ARS) des Instituts für Computertechnik der Technischen Universität Wien hat zwei wesentliche Ziele: Zum einen soll nachgewiesen werden, dass die Psyche auf der Basis des psychoanalytischen Funktionsmodells nach naturwissenschaftlichen Prinzipien wie andere Prozesse der Natur simuliert werden kann. Das konnte...

In a cognitive architecture, decision-making is the task that processes information from sensor data and stored knowledge to get appropriate action plans and actuator commands. Its aim is to make a decision in a given situation based upon available options and current goals of the system. In this paper, the decision-making process of the cognitive...

Energy efficiency in buildings depends on the way the building is operated. Therefore energy management is the key component for efficient operation. Data analysis of operation data helps to better understand the systems and detect faults and inefficiencies. The facility manager benefits from smart analysis that makes use of machine learning algori...

Artificial intelligence delivers excellent results – for example in search functions on the internet, in the high performance achieved by modern robots, and in EU projects like SENSE [Bru 12], which provided exemplary implementations for the security of Krakow Airport in Poland. Nevertheless, there still exists no robot capable of preparing and ser...

To examine the impact factors and mechanisms of the decision to switch to green electricity, we develop a socio-cognitive agent-based simulation. Following seminal research in the field of decision making we focus on emotion and social norms as core mechanisms in consumer decisions. A survey of possible consumers provides the information how to cal...

In this paper we show how simple simulation scenarios can be used to develop and test foundational functionalities of cognitive architectures, exemplified with the SiMA architecture. We present an interdisciplinary methodology that considers the challenges in capturing and evaluating basic functionalities of the human mind. In this regard, we struc...

The intention of a Smart City concept is among other things to increase the energy efficiency of a city. Typically addressed topics are energy management or urban traffic management. Up to now Information and Communication Technology (ICT) measures within a Smart City to increase energy efficiency in public lighting have not been considered in deta...

When developing a model of perceptual categorization, a functional and holistic approach is required. Therefore, considering the influence of an agent's current needs, perceptual categorization is modeled as the valuation of a stimulus regarding its potential to satisfy an agent's needs. Based on an exemplar model, an activation-based model is deve...

When developing autonomous agents, the problem of motivation poses one of the key questions. Following a bionic approach inspired by psychoanalysis, a multi-level motivational system to enable autonomous agents to pursue their own agenda and cope with their internal and external environment is presented. Considering embodiment, both homeostatic (ex...

For cognitive agents that decide based on experiences, memory retrieval is a significant issue. In this article a contribution to this field is made by introducing the concept of psychic spreading activation for memory retrieval in an autonomous agent. Using the psychoanalytical foundation of that as a constraint, a variant of spreading activation...

Evaluation and validation of software architectures in cognitive science often lack objective evaluation criteria and test mechanisms. Hence, in this article we present an in-house developed use case to evaluate the cognitive architecture ARS, together with its psychoanalytically-inspired functionalities. The use case was developed by a team of psy...
